HCV and HBV cause annually, 2000 deaths from liver cancer
in Burkina Faso. In this country, serological screening of hepatitis viruses
B and C is only systematic among blood donors. The aims of this study were;
(1) to investigate the reasons for the prescription of the screening for hepatitis
B and C; (2) to determine HCV and HBV prevalence among 462 patients attending
the Saint Camille Centre and (3) to identify patients with acute hepatitis or
with chronic hepatitis for better monitoring. From February to May 2012, 462
patients attending the laboratory of the Saint Camille Medical Centre with viral
hepatitis suspicion were screened. The hepatitis B and C serological markers
were detected through Enzyme Immuno Assay (EIA) technique using commercial reagent
kits. The clinical symptoms were also recorded for each patient. The results
revealed that, the main clinical symptoms that prompted physicians to request
HBV and HCV screenings were: asthenia (39.4%), anorexia (21.2%), abdominal pains
(19.0%), nausea (10.4%), others (10.0%). The prevalence of HbsAg was 29.4% among
the screened people. Patients with acute hepatitis B, active chronic hepatitis
B and non-active chronic hepatitis B represented 11.2, 2.2 and 16.0%, respectively.
The acquisition of immunity against HBV after vaccination was attempted for
11.7% people. HCV prevalence was 3.9% and its coinfection with HBV was 2.2%.
This study showed a high prevalence for hepatitis B and C among patients attending
Saint Camille Medical Centre. Without hygiene education and HBV/HCV prevention,
viral hepatitis infection will become a serious public health problem in Burkina
Faso. |

Background and Objective: Cervical cancer usually occurs several years after persistent infection with oncogenic or high-risk human
papillomavirus. The objective of this study was to determine carriage of 14 genotypes of high-risk human papillomavirus among women
at Orodara and then characterize the genotypes found in these women. Materials and Methods: From June to July 2015, 120 women
from the general population were recruited in the health district of Orodara. They voluntarily agreed to participate in the study.
Endocervical samples were taken from these women prior to screening for precancerous lesions by visual inspection with acetic acid and
lugols iodine. Identification of high-risk human papillomavirus genotype was done using real-time PCR. Results: High-risk human
papillomavirus prevalence was 38.3% and the most common genotypes were HPV 52 (25.4%), HPV 33 (20.6%) and HPV 59 (11.1%). The
HPV 66 was also identified with a prevalence of 9.5%. Conclusion: The HPV 16 and HPV 18 which are frequently associated with cancer
worldwide were not found among the most frequent oncogenic HPV in women in Orodara. |

Group A human rotaviruses (RVA) are the most common causes of severe viral gastroenteritis in infants and young children worldwide. The available vaccines, while effective in Europe and North America have shown a reduced efficacy in Africa. One issue raised is the genetic variability of RVA. The objective of this study was to perform a literature review of molecular epidemiology to determine the prevalence of RVA genotypes circulating in Africa so as to establish a mapping of reliable data on these various genotypes. The search for articles was done from the National Institutes of Health (PUBMED) using three set of keywords. Articles were selected with inclusion criteria such as the date of publication, the age of the children, the sample size and the diagnostic techniques (standardized laboratory techniques). The data were imported into STATA SE version 11 software. Specific prevalence was estimated with Confidence Intervals (CI) of 95%. A total of 326 published studies were initially retrieved, out of which 27 studies were finally selected for the systematic review. The selected studies cover 20 African countries. The most encountered genotypes in Africa during this period were G1 (32.72%), followed by G2 (17.17%), G3 (9.88%), G9 (8.61%) and G12 (7.56%) among the G-types. The most common P-types were P[8] (48.71%) followed by P[6] (22.60%) and P[4] (11.58%) and the G1P[8] combination (22.64%) was the most encountered followed by G2P[4] (8.29%), G9P[8] (6.95%) and G2P[6] (5.00%). North Africa presented the highest prevalence of the P[8] genotype (65.70%). This review provides a comprehensive view of the current circulating rotavirus strains in Africa, which can be important in light of the new rotavirus vaccinations. Indeed, in Africa, the pursuit of national and continental studies for epidemiological surveillance of circulating rotavirus strains is vital for the promotion of future successful vaccines. |
